What matters for project planning
The stormwater side is the part that reaches this work, because sealing a crawl space almost always depends on exterior drainage being corrected first. Where water is routed once it leaves the foundation is the regulated question, and on the rolling lots common here that route usually crosses a neighboring property or feeds a mapped drainage path -- so the parcel's drainage conditions are worth establishing before a liner is priced rather than after it fails. Historic-district information matters only where below-grade work produces a visible change at grade, such as a new exterior access or a regraded front slope on a designated property.

Verify the property, not just the city
City-level facts about Gastonia won't tell you a specific parcel's flood zone, historic designation, buffer rules, soil type, or concealed conditions. Confirm those with the city and your chosen provider before authorizing anything.
